Comment 1 Paolo Carlini 2008-01-15 10:45:41 UTC

Hi David, can you have a look at this issue? Thanks.

Comment 2 Rainer Tammer 2008-01-15 11:28:08 UTC

Hello,
currently I am working with Ralf Wildenhues (libtool, autconf, automake, config) to get AIX 6.1 in. The libtool (branch-1.5 / HEAD) and config.guess now recognizes AIX 6.1 as -> powerpc-ibm-aix6.1.0.0.

I have not yet regenerated the complete build environment of gcc 4.2.2 with the above tools. As gcc is a very large project I am not comfortable in rebuilding the whole shebang...

Comment 3 Rainer Tammer 2008-01-21 11:14:05 UTC

Hello,
any news ? 

Do you need further information / tests ?

Bye
  Rainer

Comment 4 David Edelsohn 2008-01-22 22:15:32 UTC

libsdc++ does not appear to be configured correctly on AIX 6.1.  libstdc++-3/libmath/stubs.c and /usr/include/math.h are not interacting correctly and functions, such as fabsl, are getting redefined by math.h, causing problems.

Comment 5 Rainer Tammer 2008-01-23 07:12:31 UTC

AIX 6.1 TL0 SP2 math.h

Comment 6 Rainer Tammer 2008-01-23 07:13:06 UTC

Hallo,
this is exactly what I feared. But unfortunately I do not know exactly how to fix this. I have attached the math.h from AIX 6.1. Maybe you can have a look at the header and find a quick fix ?

Bye
  Rainer

Comment 7 David Edelsohn 2008-01-24 17:23:39 UTC

I have upgraded libtool and all of the configure scripts in mainline.

The problem with stubs is because the libstdc++-v3 configure machinery is not recognizing that AIX libm already provides all of those functions, as it detects with AIX 5.  I am continuing to investigate.

Comment 8 David Edelsohn 2008-01-24 19:12:49 UTC

AIX 6 math.h "optimizations" completely confuse GCC configure looking for ISO C99 and long double support.  It looks like this will require fix-includes magic.

Comment 9 David Edelsohn 2008-01-25 02:53:30 UTC

Replacing gcc's "include-fixed" version of math.h with the include-fixed version from AIX 5.3 gets farther.  AIX 6 math.h is going to need to be tweaked and we need to figure out what parts of the file need to be commented out.  I suspect all of the "inlined" functions.

Comment 10 Rainer Tammer 2008-01-25 07:13:01 UTC

Hello,
I can try with the updated source and the AIX 5.3 math.h ...

What is the correct SNV tag for the "updated" version or did you only update you local copy ??

Bye
  Rainer

Comment 11 David Edelsohn 2008-01-25 13:58:25 UTC

The AIX 5.3 fixed math.h does not make the build completely succeed, it just gets farther.

GCC currrent mainline has the other changes.

Is this the problem you mentioned ?? 
The 4.2.2. release did not crash on this place.

First, mainline bootstraps fully for me on AIX 6.1.  I am closing this bug about AIX building libstdc++ as resolved in GCC 4.3.

Second, "... and you are right" is completely meaningless without context.  I have no idea what you are referring to.  Make sure that the process limits are large enough.  Building on AIX 6.1, I did experience random system call failures during the build, but simply restarted and the build completed.

If you can provide a more detailed and repeatable failure, please open a new GCC bug.

Comment 16 David Edelsohn 2008-01-29 14:42:52 UTC

By the way, I am using a recent GCC compiled for AIX 5.3 with the "fixed" headers removed as the bootstrap compiler on AIX 6.1.

Comment 17 Rainer Tammer 2008-01-29 15:17:01 UTC

I have used IBM XL C/C++ 9.0 to bootstrap the gcc 4.3 compiler. I will test the build with the gcc 4.2.2 build from www.perzl.org (Mr. Perzl from IBM Germany) for the initial stage1.

Thanks for your help.

Comment 18 David Edelsohn 2008-01-29 15:22:56 UTC

IBM XLC has had problems bootstrapping GCC.  I am surprised you got to libstdc++ for GCC 4.2.2.  If you were using XLC, then that likely is the problem and it miscompiled the stage1 GCC compiler.
